Disorders of hypoglossal nerve

This code signifies conditions affecting the twelfth cranial nerve, the hypoglossal nerve, which is responsible for tongue movement. Dysfunction can manifest as weakness, atrophy, or fasciculations of the tongue, impacting speech, swallowing, and oral hygiene.

Apply this code when documentation indicates a specific disorder or lesion of the hypoglossal nerve, such as paralysis, paresis, or neuropathy. Supporting documentation should clearly identify the hypoglossal nerve as the affected cranial nerve.

• Differentiate from generalized neuropathies or other cranial nerve disorders.
• Specify laterality (e.g., right, left, bilateral) if documented, using appropriate subcodes.
• Ensure the physician's documentation explicitly links the symptoms to hypoglossal nerve involvement.
